CROSS REFERENCE TO RELATED APPLICATIONS

This application is a national stage filing under 35 U.S.C. 371 of PCT/US2010/027292, filed 15 Mar. 2010, which claims priority to U.S. Application No. 61/164,636, filed 30 Mar. 2009, the disclosure of which is incorporated by reference in its/their entirety herein.

TECHNICAL FIELD

The present invention relates to a wire management article and, more particularly, to a wire management article including structural elements that project from a base layer for holding a plurality of discrete wires in a side-by-side relationship.

BACKGROUND

Articles for identifying and organizing wires used, e.g., to route signals or power between electrical devices, are known in the art. For example, it is known in the art to use wire ties to route and group wires. These wire ties wrap around a group of wires but provide no further organization and do not allow for ease of identification and removal or addition of a single wire. For example, when a single wire needs to be removed or traced during installation or debug of an electrical system routing a large number of parallel wires, the installer must either unthread the group of wires from a number of wire ties or destroy the wire ties. After this, the installer will have to re-thread the group of wires or install new wire ties resulting in additional time, effort, cost, and waste.

Although many useful articles have been developed to identify and organize wires, there is still a need in the art for a wire management article that is inexpensive, reliable, and provides identification, organization, separation, protection, design flexibility, and ease of access and removal to a group of wires without destruction of the article or the wires or a laborious unthreading/re-threading process.

SUMMARY

In one aspect, the invention described herein provides a wire management article including a base sheet and a plurality of wire management elements. The base sheet has a major surface from which the wire management elements project. The wire management elements define a plurality of channels. Each channel is configured to retain at least one wire.

The above summary of the present invention is not intended to describe each disclosed embodiment or every implementation of the present invention. The Figures and detailed description that follow below more particularly exemplify illustrative embodiments.

Now referring to FIGS. 13a-13b and 14a-14b , a wire management article according to an aspect of the present invention may be configured to retain wires in a generally non-parallel stacked arrangement, e.g., to electromagnetically isolate two or more individual wires or groups of wires from each other. Retaining wires in a generally non-parallel stacked arrangement reduces crosstalk between wires relative to retaining wires in a generally parallel stacked arrangement. A specific example includes retaining wires in a generally perpendicular stacked arrangement, e.g., to mitigate transverse electromagnetic mode (TEM) influences from power transmitting wires. Another way to electromagnetically isolate two or more individual wires or groups of wires from each other is to place a ground plane (not shown), such as, e.g., a metal shield, between the two or more individual wires or groups of wires. This ground plane may be housed in the wire management article or may be inserted between the two halves of a bi-fold wire management article, such as, e.g., wire management article 2002 shown in FIG. 12c , and may be electrically grounded to the support to which the wire management article is mounted, e.g., by connecting the ground plane to a mechanical fastener, such as, e.g., a screw, mounting the wire management article to the support.

A non-parallel stacked arrangement of wires can be obtained with a one-piece construction, such as, e.g., the wire management article shown in FIGS. 13a-13b , or with a multi-piece construction, such as, e.g., a two-piece construction, such as, e.g., the wire management article shown in FIGS. 14a -14 b.

Wire management articles according to aspects of the present invention may be combined to form a variety of wire management systems according to aspects of the present invention. The wire management articles may be seen as modular building blocks that are capable of building a variety of wire management systems. For example, a wire management system may be built by stacking two or more wire management articles as shown in FIGS. 16a-16b and 17a -17 b.

FIGS. 16a-16b illustrate an exemplary embodiment of a wire management system according to an aspect of the present invention. Wire management system 2900 includes a first wire management article 2902 and a second wire management article 2902′ configured to be releasably attached to first wire management article 2902. First wire management article 2902 includes a first base sheet 2904 and a plurality of first wire management elements 2906. First wire management elements 2906 project from a top surface 2904 a of first base sheet 2904 and define a plurality of first channels 2912. Each first channel 2912 is configured to retain at least one wire 14 and a connection element of second wire management article 2902′, which is described below and best shown in FIG. 16b . Second wire management article 2902′ includes a second base sheet 2904′ and a plurality of second wire management elements 2906′. Second wire management elements 2906′ project from a top surface 2904 a′ of second base sheet 2904′ and define a plurality of second channels 2912′. Each second channel 2912′ is configured to retain at least one wire 14. Second wire management article 2902′ further includes two connection elements 2962′ projecting from a bottom surface 2904 b′ of second base sheet 2904′. In other embodiments, one or more connection elements 2962′ may project from bottom surface 2804 b′ of second base sheet 2904′ as is suitable for the intended application. Connection elements 2962′ are configured to cooperate with corresponding first wire management elements 2906 of first wire management article 2902 to releasably attach second wire management article 2902′ to first wire management article 2902. As shown in FIG. 16b , each connection element 2962′ includes a connection portion 2964′. In this embodiment, connection portions 2964′ have a cylindrical rod shape and are generally parallel to second channels 2912′.

Second wire management article 2902′ may be referred to as “parallel piggyback option carrier”, wherein second wire management article 2902′ is stacked on first wire management article 2902, and second channels 2912′ are generally parallel to first channels 2912. In general, this arrangement allows wires 14 retained by second wire management article 2902′ to be generally parallel to wires 14 retained by first wire management article 2902. In the illustrated embodiment, this arrangement facilitates pulling selective wires 14, such as, e.g., process control signal wires, from first wire management article 2902, routing them through second wire management article 2902′, and connecting them to a terminal block 2966 without using conventional ties or clamps.

FIGS. 17a-17b illustrate another exemplary embodiment of a wire management system according to an aspect of the present invention. Wire management system 3000 is similar to wire management system 2900 illustrated in FIGS. 16a-16b . Whereas in wire management system 2900, connection portions 2964′ are generally parallel to second channels 2912′, in wire management system 3000, connection portions 3064′ are generally perpendicular to second channels 3012′.

Second wire management article 3002′ of wire management system 3000 may be referred to as “perpendicular piggyback option carrier”, wherein second wire management article 3002′ is stacked on first wire management article 3002, and second channels 3012′ are generally perpendicular to first channels 3012. In general, this arrangement allows wires 14 retained by second wire management article 3002′ to be generally perpendicular to wires 14 retained by first wire management article 3002. In the illustrated embodiment, this arrangement facilitates connecting wires 14 retained by second wire management article 3002′, such as, e.g., process control signal wires, to a terminal block 3066 while mitigating transverse electromagnetic mode (TEM) influences from wires 14 retained by first wire management article 3002, such as, e.g., power transmission wires, on wires 14 retained by second wire management article 3002′.

Instead of a cylindrical rod shape, in other embodiments, connection portions 3064′ may have a ball shape or any other suitable shape. Ball-shaped connection portions allow second wire management article 3002′ to be placed such that second channels 3012′ are generally parallel, generally perpendicular, or at any suitable angle relative to first channels 3012. A plurality of ball-shaped connection portions may be placed in an array.

Wire management articles according to aspects of the present invention may include various structures and methods to identify a single channel or wire, or a group of channels or wires retained therein.

A single channel or group of channels of a wire management article according to an aspect of the present invention may include a channel identifier to identify the location of the channel or group of channels relative to other channels or groups of channels. This allows a wire installer to quickly determine the location of a specific wire or group of wires retained in the wire management article. The channel identifier may include a color code, a character code, or a distinctive wire management element. Examples of a character code include alphabetical codes, numerical codes, and alpha-numerical codes. Examples of a distinctive wire management element include taller or wider posts/ridges. Color coding may also be used to guide the wire installer in placing the correct wire in the correct channel. For example, the channels may have substantially the same color as the corresponding wires. Alternatively, the base sheet of the wire management article may have a contrasting color (or appearance) to the wire management elements to clearly show where the wires are to be placed.

A cover sheet of a wire management article according to an aspect of the present invention may include a wire group identifier to identify a group of wires. This would allow a wire installer to quickly determine the location of a specific group of wires retained in the wire management article. In one exemplary embodiment, returning to FIG. 11a , cover sheet 1316 of wire management article 1302 includes a top surface 1316 a opposite bottom surface 1316 b and a wire group identifier 1368 disposed on top surface 1316 a. Wire group identifier 1368 may include a direct marking, such as, e.g., writing or printing directly on top surface 1316 a, or a pre-printed label.

In each of the embodiments and implementations described herein, the wire management article and elements thereof are formed of any suitable material. The materials are selected depending upon the intended application and may include both metals and non-metals (e.g., any one or combination of non-conductive materials including but not limited to polymers, glass, and ceramics). Material selection will depend upon factors including, but not limited to, chemical exposure conditions, environmental exposure conditions including temperature and humidity conditions, flame-retardancy requirements, material strength, and rigidity, to name a few.

In each of the embodiments and implementations described herein, the wire management article and elements thereof are formed by methods such as, e.g., profile extrusion or replication extrusion. Co-extrusion or other enhancements may be used in combination to provide unique material constructions that give rise to useful product characteristics. For example, interlocking wire management elements, cover sheet hinge portions, and pull tab hinge portions may be formed from an elastomeric material for enhance durability. Another co-extrusion option is to form single- or multi-colored stripes or “lanes” to more clearly identify where a wire should be located. After forming the wire management article, it may be post-processed, e.g., to change the shape of elements thereof. Example post-processes include a flame treatment or heated nip rolls to form the head portions of the wire management elements. Another example post-process includes cutting slots laterally in the elongated ridges at intervals along the length of the ridges, which may provide additional flexibility of the wire management article. After wire management articles are formed in an extruded film or sheet, an adhesive layer or backing may be attached to the film or sheet, after which the wire management articles can be singulated.

Although specific embodiments have been illustrated and described herein for purposes of description of the preferred embodiment, it will be appreciated by those of ordinary skill in the art that a wide variety of alternate and/or equivalent implementations calculated to achieve the same purposes may be substituted for the specific embodiments shown and described without departing from the scope of the present invention. Those with skill in the mechanical, electro-mechanical, and electrical arts will readily appreciate that the present invention may be implemented in a very wide variety of embodiments. This application is intended to cover any adaptations or variations of the preferred embodiments discussed herein. Therefore, it is manifestly intended that this invention be limited only by the claims and the equivalents thereof.
